The solution – Electrifying heat (& decarbonising electricity) • But – What might this do to ‘peak electricity’ demand? • What do we know? • What do we need to do?
Stratified random sample – N ~= 4000 households – http://www.energy.soton.ac.uk/save-data-sources/ • New Plymouth/Hawkes Bay – Convenience sample – N ~= 40 households – https://dx.doi.org/10.5255/UKDA-SN-853334 Monitoring Data cloud Analysts • W every 10s • Wh every 15 min • W every 60s
The solution – Electrifying heat (& decarbonising electricity) • But – What might this do to ‘peak electricity’ demand? • What do we know? – Not a lot... • What do we need to do? But the peak(s) will get peakier
